Abstract: A process and an arrangement for generating control signals in a predeterminable phase position relative to an alternating voltage at an at least short term-stable frequency through the utilization of a higher-frequencied, at least short term-stable auxiliary timing pulse. The process contemplates determining the duration of a presettable number of periods of the alternating voltage, in which there are counted the periods of a first auxiliary timing pulse occurring within this duration; counting the periods of a second auxiliary timing pulse of a different frequency which is correlated over a period of time with the first auxiliary timing pulse; and upon coincidence of the period count of the first and second auxiliary timing pulses, generating the control signal. The circuit arrangement consists of standard digital circuits. In particular, with the utilization of the circuit arrangement within the broader circuit concept, can there be employed an already present synchronizing or timing pulse frequency generation of suitable type inasmuch as, besides the adequate level of the timing pulse frequency, no special requirements are set on the quality of the timing pulse.
